Subject: [linux-lvm] [PATCH 0/2] boot to a mapped device
Date: Wed, 26 Sep 2018 02:00:45 -0300	[thread overview]
Message-ID: <cover.1537936397.git.helen.koike@collabora.com> (raw)

This series is reviving an old patchwork.
Booting from a mapped device requires an initramfs. This series is
allows for device-mapper targets to be configured at boot time for
use early in the boot process (as the root device or otherwise).

Example, the following could be added in the boot parameters.
dm="lroot,,,rw, 0 4096 linear 98:16 0, 4096 4096 linear 98:32 0" root=/dev/dm-0

  init: add support to directly boot to a mapped device
